以1-羟基异喹啉为原料合成4-溴-1(2H)-异喹啉酮的一般步骤:向含有异喹啉-1(2H)-酮(105 mg,0.723 mmol)的DMF(2 mL)溶液中加入N-溴代琥珀酰亚胺(NBS,142 mg,0.796 mmol)。将反应混合物在室温下搅拌2小时。反应完成后,将混合物浓缩以去除溶剂。粗产物通过制备型高效液相色谱(HPLC)进行纯化,得到中间体6 4-溴异喹啉-1(2H)-酮(110 mg,产率68%)。[C] MS(ESI)m/z:223.9(M + H)+。1H NMR(500 MHz,DMSO-d6)δ11.57(br.s,1H),8.24(dd,J = 8.0, 0.8 Hz,1H),7.88-7.83(m,1H),7.79-7.75(m,1H),7.61(ddd,J = 8.0, 7.1, 1.1 Hz,1H),7.55(s,1H)。
